Answer:
0
Step-by-step explanation:
3ab + 5b - 6 when a = -1 and b is 3
→ First substitute a and b into 3ab
3 × -1 × 3 = -9
→ Substitute b into 5b
5 × 3 = 15
→ Connect all the terms together
-9 + 15 - 6
→ Simplify
0
First is 7 second is 8 third is 3
Since these are supplementary angles (two angles which sum to 180°) we can say:
4x+x=180 combine like terms on left side
5x=180 divide both sides by 5
x=36°
Answer:
